At the moment I'm using a lot of TopLine wheels and I really like them a lot. They are very tough, look good and have a deep hex so no problem if you need to space them out a bit.

I would recommend using original wheels only, not the clone crap from R2hobbies and similar shops. Sure, there might be a few good clones around (I have a set that's still good after lots of bashing) but in the end it is not that much cheaper than the real stuff and taking the risk of breaking them for a few bucks isn't worth it IMO. + Supporting the original makers is always good, so they can create more awesome designs. Remember that R&D costs a LOT!
